25. Diffusion  Students placed a raw egg without its shell into a highly concentrated solution of sugar. If the amount of sugar in the solution is greater than in the egg, which of these is most likely to occur?  AWater will flow into the egg and cause the egg to expand.  BWater will flow out of the egg and cause the egg to shrink.  CThe sugar will dissolve the egg.  DThe sugar will break the egg into pieces.
